Anxious to attract the sort of high-performance buyers increasingly drawn to European sports cars from the likes of Porsche, Ferrari and Lamborghini, General Motors is planning some major changes for the next-generation Chevrolet Corvette – starting with a high-revving, small-displacement powertrain, that will substitute for the big V8s traditionally found under the hood of the Chevy 2-seater.
TheDetroitBureau.com has learned that GM has approved the use of a very European-style V8 that will be only slightly larger than 3 liters in displacement. The engine will be of an overhead-cam, rather than traditional overhead-valve design, using a dry sump oil system that’s particularly well-suited to high-performance road courses rather than straight-line acceleration. The engine is expected to feature a narrow 80.5 mm bore and a long stroke, more like a Ferrari or Lamborghini powertrain than the approach used for traditional Motor City metal.
A very senior GM executive also confirmed that the new engine will be turbocharged, which will help yield a broad torque curve and maximum performance under a variety of driving conditions. The engine is expected to deliver in excess of 400 horsepower, which means a specific output in the range of 125 horsepower per liter. That’s the sort of number that would help the next-gen Vette stack up well against the likes of a Porsche 911 or Lamborghini Gallardo.
